blender spot light

이전 렌더링에서 빛이 산란하지 않고 그냥 레이저 처럼 직사로 와서

그림자가 완전 각지는 문제가 있었는데

그걸 이렇게 하면 좀 부드럽게 퍼진다고 한다.

아래는 claude 가 개선한 코드인데

        light_data.energy = random.uniform(*LIGHT_ENERGY_RANGE)
        light_data.shadow_soft_size = random.uniform(*LIGHT_SHADOW_SOFT_SIZE_RANGE)
        light_data.spot_size = random.uniform(*LIGHT_SPOT_SIZE_RANGE)
        light_data.spot_blend = random.uniform(*LIGHT_SPOT_BLEND_RANGE)

energy는 power에 대응되는것 같고, shadow_soft_size는 radius에 대응되는것 같다.

아 쫌 용어 통일하라고 ㅠㅠ api에 맞추던가 아니면 api를 ui에 맞추던가!

energy
The energy this light would emit over its entire area if it wasn’t limited by the spot angle, in units of radiant power (W) (in [-inf, inf], default 10.0)

shadow_soft_size
Light size for ray shadow sampling (Raytraced shadows) (in [0, inf], default 0.0)

spot_size
Angular diameter of the spotlight beam (in [0.0174533, 3.14159], default 0.785398)

spot_blend
The softness of the spotlight edge (in [0, 1], default 0.15)

[링크 : https://docs.blender.org/api/current/bpy.types.SpotLight.html]

초기값

power 올림

radius 0.2로 변경

blender eevee / cycle 렌더 헤드리스

노트북에서는 오히려 학습 데이터 생성이 빠른데

데스크탑에서 느려서 확인해보니

노트북에서는 이렇게 nvtop 돌리니까 gpu를 사용한다.

아무튼.. claude 말로는 cycles 돌리면 빨라진다는데 흐음.. cycles는 raytracing쪽 설정때문에 잘 모르겠던데..

eevee는 gpu 렌더러라 gpu가 없으면 작동안한다고. 그런데 왜.. headless 구성에 영향을 받지?

EEVEE is a GPU renderer. You cannot use it without a GPU. It can only use GPU to render, doesn't even support CPU rendering. This means it uses whatever week GPU you have and, sure it can run out of memory and stop being able to cope very quickly.

[링크 : https://blender.stackexchange.com/questions/328484/when-using-rendering-in-blender-using-eevee-without-a-gpu-does-lighting-behave]

[링크 : https://blender.stackexchange.com/questions/230728/is-there-no-way-of-rendering-headless-using-eevee]

CPU Rendering
Being a rasterization engine, EEVEE only uses the power of the GPU to render. There is no plan to support CPU (software) rendering as it would be very inefficient. CPU power is still needed to handle high scene complexity as the geometry must be prepared by the CPU before rendering each frame.

[링크 : https://docs.blender.org/manual/en/latest/render/eevee/limitations/limitations.html#cpu-rendering]

아무튼 bpy 에서는 아래처럼 cycles를 설정하면 헤드리스 설정이라도 gpu 가속 잘 받는다고

scene = bpy.context.scene

scene.render.engine = "CYCLES"
scene.cycles.device = "GPU"
scene.cycles.samples = CYCLES_SAMPLES
scene.cycles.use_denoising = CYCLES_USE_DENOISING

blender 창 나누기. 카메라 뷰 보기

창을 띄우고 모델을 불러오고

창 크기 조절하듯 경계선 밖에 가서 + 로 커서가 바뀌었을 때 우클릭하면

아래처럼 split / join이 뜬다.

그럼 split 해주고

원하는 창을 나누고 클릭하면 된다.

오른쪽 창은 숫자키패드 0 눌러서 카메라 뷰로 바꾸고

왼쪽에서 조절하면 렌더하면서 일일이 안봐도 되서 딱이네

다시 빌드 하고 시도

$ sudo apt install gcc-10 g++-10
$ git clone --depth 1 https://github.com/NVIDIA/cuda-samples.git
$ cd cuda-samples/Common
$ sudo cp helper_math.h /usr/include

$ cd ~/src/libfreenect
$ mkdir build_cuda
$ cd build_cuda
$ cmake .. -DENABLE_CUDA=ON -DCUDA_HOST_COMPILER=/usr/bin/gcc-10

~/ros2_ws$ vi ./src/kinect2_ros2/kinect2_bridge/launch/kinect2_bridge_launch.yaml

31 value: "default"

kinect2를 인식해서 좋긴한데

dpeth_method / reg_mothod가 cpu로 돌아가는건지 cuda를 쓰는건지 모르겠다.

2% 지만 소비전류가 늘은거 보면 쓰는건 맞는거 같은데.. 성능 왜이러냐

그러니 Depth Map Topic과 Color Image Topic을 지정해주면

아래처럼 먼가 컬러로 나오긴 한다.

근데 slam은 어떻게 하지?

udev는 user space device 라고 해야하나.. 아무튼 좋은거(!)

아래 경로에 설정 파일들이 있고

/etc/udev/rules.d/

이전에 추가되었던것들 열어보면 아래와 같은 내용들이 있어서

해당되는 VID나 PID가 존재하면 옵션에 따라 장치를 생성해준다.

$ cat 90-kinect2.rules

요건 stlink. 어떤 장치명으로 붙게 하려고 이렇게 하나본데..

아래는 명령어별 출력 포맷

$ udevadm info -a /dev/ttyUSB0

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.
